Associate Editors can recommend the rejection of an article to the Chief Editor, who needs to check that the authors rights have been upheld during the peer-review process, and who can then ultimately reject the article if it is of insufficient quality, has objective errors or if the authors were unreasonably unwilling to address the points raised during the review. No use, distribution or reproduction is permitted which does not comply with these terms. The trend and rate of change of water requirement of maize in different reproductive periods were different, and all reproductive stages showed a decreasing trend on the whole (Shown in Figure 2). Exploring the trends of crop water requirements in time series and the attribution analysis are important for agricultural irrigation and water resources allocation.

The relationship between crop water requirements and meteorological factors can be investigated from two perspectives: full fertility and sub-fertility stages, each of which has its own growth and management requirements (Muneer et al., 2018; Mthembu et al., 2022), and different fertility stages have different sensitivity to meteorological factors (Luo and Batur, 2017; Xue et al., 2018). Signal Processing has applications in diverse fields, including telecommunications, medicine, multimedia, biometrics, and finance, among others. Comparative study on different sowing dates of spring maize in Weibei, Shaanxi Province. The conference welcomes contributions on all aspects of signal processing, including theory, algorithms, applications, and hardware implementations. The Frontiers platform enables post-publication commenting and discussions on papers and hence the possibility to critically evaluate articles even after the peer-review process. The variation of maize water requirement with temporal stages had minimal effect on the overall trend of spatial distribution.

Frontiers has a community retraction protocol in place to retract papers where serious concerns have been raised and validated by the community that warrant retraction, including ethical concerns, honest errors or scientific misconduct. Maize water requirement at jointing stage increased from north to south, and reached the minimum in the central and southern part of Ankang City in southern Shaanxi Province. (2011). Assess. The spatial distribution of maize water requirement during the whole reproductive period and each reproductive stage is shown in Figure 4, which shows an overall decreasing trend from north to south during the whole reproductive period of maize in Shaanxi Province, with a range of 180.37640.26mm for the first period and 174.29610.05mm for the second period (Shown in Figure 4A). Crop coefficients: The piecewise single value average method recommended by FAO-56 in 1998 was adopted to calculate the crop coefficient, which should be revised according to the actual local situation when used.

The data analyzed in this study is subject to the following licenses/restrictions: Data Availability Statement: Not applicable. objectively through quantitative online article level metrics, is The distribution of water resources in Shaanxi Province is more in the north and less in the north, but the distribution of water requirement is more in the north and less in the south, which indicates that spatial water transfer is needed for irrigation to meet crop growth requirements. Frontiers is fully compliant with open access mandates, by publishing Impact Factorand CiteScore. on their articles, except for any third-party images and other materials J. Shaanxi Meteorology (4), 15. The promoting effect of average temperature and wind speed gradually decreased from north to south. TABLE 5. 27 (4), 2230. Article processing charges (APCs) apply to articles that are accepted for publication by our external editors, following rigorous peer review. Where is the slope of saturated water vapor pressure-air temperature curve, kPa/C; Rn is the net radiation on crop surface, MJ/(m2d); G is the soil heat flux, MJ/(m2d); is the psychrometric constant, kPa/C; T is the mean daily air temperature,C; U2 is the wind speed at 2m height above the ground, m/s; es is the saturated water vapor pressure, kPa; and ea is the actual water vapor pressure, kPa. The inhibiting effect of water vapor pressure on the water requirement of maize at the tasseling stage was the greatest. Reviewer identity is protected at this stage to safeguard complete freedom of opinion. Wang and Niu (2014) studied the summer maize water demand in the Guanzhong irrigation area and obtained values between 400 and 500. Under the (10), 137139. Supplementing this part of research can save water resources for agriculture and alleviate the contradiction of water supply in Shaanxi Province. The degree of influence of meteorological factors was inconsistent at different stages of fertility, for example, the contribution of sunshine hours to maize water requirement was increasing at each stage of fertility, increasing by 11.67%, 8.81%, 2.39%, and 13.61%, respectively. (2009) studied the national crop water requirement and analyzed in the Jin-Shaan-Gan region and obtained the conclusion that the water demand of spring maize crop is between 450 and 750mm while that of summer maize is between 250 and 450mm. http://www.isaacpub.org/AboutThisJournal.aspx?ids=22, 24th International Congress on Reproductive Biomedicine and the 19th Congress on Stem Cell Biology & Technology, 18th Edition of International Conference on Catalysis, Chemical Engineering and Technology (CCT 2024), 2nd International Conference on Nursing Care and Patient Safety, Great Openings and Closings for Presentation, Frontiers in Signal Processing is an open-access journal devoted to publishing theoretical and practical research in all aspects of signal processing. (2017). Photos used throughout the site by David Jorre, Jean-Philippe Delberghe, JJ Ying, Luca Bravo, Brandi Redd, & Christian Perner from Unsplash. Vol 1 . Chin. From the national spatial distribution, the water requirement of maize in the northwest is higher than that in the southeast. This paper proposes an end-to-end method for ego-velocity estimation based on radar scan registration. humankind. FIGURE 1. (5) From the results of the path analysis, it can be seen that the average temperature and sunshine hours are the key factors influencing maize water requirement in Shaanxi Province, both by region and by time period, and have an enhancing effect on water requirement, while wind speed has an enhancing effect on water requirement but is not significant.
